What is valr?

valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.

valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.

What is vcfR?

A genomics workhorse whose visible release feed stops dead in mid-2020.

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.

◆ Current state

valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.

◆ Where it's heading

Two arcs converge here. One is compatibility: min_overlap arrived with a deprecation warning in 0.9.0 and its default flipped from 0 to 1 in 0.10.0, so book-ended intervals are excluded by default as bedtools does, with the internal calculations in bed_closest() and friends deliberately left counting them. The other is the file-backed path, which grew out of the cpp11bigwig dependency adopted in 0.8.3 for read_bigwig() and re-exported in 0.9.0 — reading a file became querying one. Underneath, the C++ base keeps getting lighter: Rcpp swapped for cpp11, rlang cut to a single function, per-group memory copies removed from three verbs.

◆ Prediction

Only five verbs take a file argument today and bed_closest(), bed_glyph() and the statistical verbs do not, so extending the file-backed path across the rest of the API is the obvious follow-up. The deprecated tibble re-exports and the now-defunct n_fields argument suggest continued removal of the compatibility layer in the next minor release.

A genomics workhorse whose visible release feed stops dead in mid-2020.

◆ Current state

vcfR reads, manipulates and visualises VCF files, the standard format for genomic variant calls, and bridges them into R population-genetics classes such as genind, genlight and DNAbin. The three entries available here all come from the first half of 2020 and stop there, so the feed shows the state of the package six years ago rather than today.

◆ Where it's heading

Within that window the direction is unmistakably consolidation, not growth. 1.9.0 pushed error handling down into the C++ layer that actually reads the VCF so failures surface earlier and shared files stop tripping a readability pre-check, tightened class checks, and added conversion options. The two releases after it exist only to keep pace with R 4.0.0 and dplyr 1.0.0. Any development after June 2020 is not visible in this feed, so the current trajectory cannot be read from it.

◆ Prediction

No prediction can be grounded in these entries — the feed has been silent for six years, which points at a stale or broken source rather than at a package that stopped.
